House Massey of Stonedance is a noble house from Stonedance in the crownlands. They blazon their arms with a triple spiral; red, green and blue, on white, an ancient sigil for an ancient House.
The Masseys are a house of First Men origin. Lord Maldon Massey, a vassal of the Storm King Durran the Ravenfriend, built Stonedance and ruled Massey's Hook. The Masseys broke away from House Durrandon during the reign of King Durwald the Fat, however. The Masseys were one of the many houses which historically claimed the mouth of the Blackwater Rush.
The Masseys returned to the dominion of Storm's End when the Storm King Qarlton II took Stonedance after besieging the castle for a year and slaying King Josua Massey. Not even two years later, however, Josua's daughter married the Andal warlord Togarion Bar Emmon, who expelled Qarlton's men from Stonedance and replaced them with Josua's son. The Andals eventually made peace and intermarried with the Durrandons, however.
Prior to the War of Conquest, House Massey was sworn to House Durrendon of Storm's End but had closer ties to House Targaryen of nearbyDragonstone. When Aegon the Conqueror launched his invasion of Westeros, the Masseys supported him instead of the Storm King, Argilac the Arrogant. The master of laws for King Aegon I was Triston Massey. With the creation of the crownlands after the Conquest, the Masseys became sworn to the Targaryens of Aegon's new capital, King's Landing, instead of House Baratheon of Storm's End, who had replaced the Durrandons.
Lord Gormon Massey was killed attempting to tame Vermithor on Dragonstone during the Dance of the Dragons.
When Lord Bloodraven marched on Whitewalls to quash the Second Blackfyre Rebellion, among the houses who came in support was House Massey.
